Faster - Longer - Cheaper - The best buffer by pHar!

pHix-up® offers fast-acting and persistent buffering,
helping to reduce heat stress and lameness.

The video below shows a simple test comparing the relative pH values of pHix-up®
and sodium bicarbonate:


  • acts faster on rumen pH

  • persists for longer

  • is proven to increase milk yield and fat content

  • improves hoof health

  • improves fertility

  • costs less than half the daily cost of sodium bicarbonate


pHix-up® is formulated from three sources of magnesium oxide, blended together in a very fine powder that has maximum surface area for bioavailability.


Only 70g of pHix-up® is required in the diet daily, compared with a minimum of 250g of sodium bicarbonate.

Introducing the pHix-up® App:

pHix-up® is now being fed to over 300,000 cows worldwide. It’s available from your feed merchant, or for more details, please get in touch with Greg Dunn on 01206 381521.
